To LLZZ whom, it may concern:

Be it known that I, FRANK H. VVHEELooK, a citizen of the United States, residing at WVashington, District of Columbia, have invented certain new and useful Improvements in Hotater Radiators, of which the follow- .ing is a specification.

This invention relates to a new and useful improvement in devices for heating water in a containing-receptacle, more particularly to radiators to which a heater is attached for heating water in the radiator.

The invention consists in. the construction, hereinafter pointed out and claimed, of a water-heater in which there are several parallel chambers for water, such chambers communicatingwith one another at their ends, so that there may be side by side sev eral columns of water of different degrees of temperature.

In the annexed drawings, Figure l reprerents a perspective view of a radiator provided with the device; Fig. 2, an enlarged vertical section showing the interior construction of the device; Fig. 3, a perspective view of the case or jacket; Fig. 4, a transverse section on line 4 4, Fig. 2, looking down; Fig. 5, an enlarged detail of the bottom of the pipes.

In the drawings the numeral 1 represents a radiator or a water-containing receptacle, having on top the expansion-tank 2 and on one side the top nipple 3 with exterior threads 4 and the lower nipple 5 with exterior threads 6. Engaging the treads 4 of the top nipple 3 are the inner threads 7 of the upper end 8 of a curved elbow 9, having the lower end 10 with inner threads 11. Engaging the threads 6 of the lower nipple 5 are the inner threads 12 of the lower end 13 of a curved elbow 14, having the upper end 15 with the inner threads 16. Engaging the threads 11 of the elbow 9 is the upper threaded end 17 of a vertical pipe 18, the lower threaded end 19 of which engages the threads 16 of the elbow 14. The nipples 3 and 5, the elbows 9 and 14, and the pipe 18 thus make a continuous passage from the bottom to the top of the radiator on the outside.

l/Vithin the outer pipe 18 is located a mid" dle pipe 20 shorter than the pipe 18, its ends 21 and 22 being within the ends of the pipe 18. At its ends 21 and 22 the pipe 20 is made with outer and inner prongs or projections 23 24, which may be made by simply forcing outwardly and inwardly portions of the metal of the pipe 20, as shown in Fig. 5. These prongs 23 24 form spacers. Within the pipe 20 is placed a central or inner pipe 25, the ends 26 27 of which extend beyond the ends 21 22 of the middle pipe 20, but not out to the ends of the outer pipe 18. WVhen the middle pipe 18 and the inner or central pipe are put in place within the outer pipe 18, pressure applied at the prongs or spacers 23 24 will bind the three pipes together at the prongs or spacers and the three pipes will be held firmly together in the location and position shown in Fig. 2. Seated upon the upper end 15 of the elbow 14 and surrounding the lower end 19 of the outer pipe 18 is a gas burner 18 of any suitable construction, hav- 7 ing the gas-supply-pipe nipple 29. Surrounding the details thus described is the case or jacket 30. This consists of two semicylindrical halves or lengthwise parts 31 32. One half 21 has the rib 33 with the inside groove 34, and the other half 32 has the lip 35, adapted to the groove 34. The half 32 has the top notch 36, so that it may be slipped about the nipple 3.

In use the radiator is supplied with water in the usual way and of the usual quantity. Heat is applied from the burning gas at the burner 29. As the water in the outer pipe 18 outside of the middle pipe 20 first becomes heated, it rises up through the elbow 9 and passes through the nipple 3 into the top of the radiator, water flowing from the radiator.

at the bottom through the nipple 5 and elbow 14 into the bottom of outer pipe 18. As

the heat increases it is transferred through the water in the outer pipe 18 and through the middle pipe 20 to the water in this middle pipe 20, and as this water becomes heated it also rises and passes with the water from the pipe 18 into the top of the radiator, water coming in from below. This produces a free passage of water up the pipes 18 and 20 from the bottom to the top of the radiator, the water being heated on its way. By the arrangement of these two pipes the water in them is of different degrees of temperature, the water in the outer pipe 18 receiving heat directly from the gasburner, while the water within the pipe 20 is heated from the water in the pipe 18. The water from both pipes 18 and 20 meets and commingles at the tops of these two pipes. Ina device of this character the circulation through the radiator is due to the hot water entering at the top becoming cooled, falling to the bottom of the radiator,

, inner pipe 25.

and passing into. the bottom of the heater, where it is reheated and the circulation kept up. This, however, is an ideal method. EX- perience proves that the water in arriving at the top is not all heated to the proper degree, but that with the heated particles there are particles which have not the due degree of heat and which have to be carried around through the radiator, chilling the other or heated particles, so that the heated water does not yield as quickly, readily, and efiiciently heat in proportion to the fuel consumed'. It is the especial function of this invention to return these imperfectly-heated particles immediately to the heater without having them pass through the radiator. This is accomplished by means of the central or The water in the outer pipe '18 receives immediate heat from the products of combustion and theoretically is heated to the proper temperature. The water in the middle pi e 20'forms a jacket around the centralor middle pipe 25 and prevents the low ering ofthe temperature in the pipe 18 by the lower temperature of the column of water in the pipe 25. As the columns of water in the pipes 18 and 20 reach the top of the heating device there will be a downflow through the central or middle pipe 25. This is induced by the necessarily different temperature in these pipes. The water in the outer pipe 18, being the hottest, naturally rises, the waterin the pipe 25 being the coldest, and by the intervening moderately-heated column in the pipe 20 heat from pipe 18 is kept from it, falls. Thus there is a constant circulation kept up through the heater. By the ends of the pipe 25 extending beyond the ends of the pipe 20 efficiency of action is obtained. The described circulation through the heater begins as heat is applied theretoand continues with gradually-diminishing effect until a free-cir culati'on is established through the radiator, and the entire body of water is raised to the maximum tem erature The case or jacket 30 is put into p lace by slipping the notch 36 around the nipple 3 and then the half 31 is put on the half 32 by sliding the rib 33 along the lip 35.

In Fig. 6 is. shown a modification of the case-0r jacket, where it is made flat to fit over flat heating pipes. Either form of this jacket is attachable to and is removable from the heater without separating the heater from the radiator. This is especially valuable in packing the device for transportation, as the jacket is shipped separate from the heater and may be put into place by any one.

Having described my invention, what I claim is 1. A radiator or water-containing receptacle in combination with a water-heater connected and communicating at top and bottom with such receptacle and having parallel chambers one within another and communicating with one another at their ends and a burner located at the bottom of the heater, as set forth.

2. A water-heater consisting of parallel chambers one within another and connected and communicating with one another at their ends such heater having an inlet and outlet at bottom and top adapted to be brought into communcation with the outlet and inlet respectively of a radiator or water-containing receptacle in combination with a burner located at the bottom of the heater as set forth.

3. A radiator or water-containing receptacle in combination with a heater connected and communicating at top and bottom with i such receptacle and having an outlet heatingchamber, a middle heating-chamber and a central chamber concentrically arranged one within another and communicating with one another at their ends and a burner locatedat the bottom of the heater as set forth.

4. A water-heater consisting of an outer pipe, a middle pipe and a central pipe, arranged concentrically, the ends of the central pipe projecting beyond the ends of the middle pipe, the pipes communicating with one another at their ends, such heater having an inlet and outlet at bottom and top adapted to be brought into communication with the outlet and inlet respectively of a radiator or water-containing receptacle in combination with a burner located at the bottom of the heater as set forth.
